The present invention relates to a container for hazardous detergents which is adapted to permit withdrawal of the hazardous detergent (73) and recovery thereof in polluted state, the hazardous detergent (73) preferably being a solvent which can be pumped out of the container (9), is useful for internal and/or external cleaning of spray guns (1) or other polluted implements and recoverable in the container (9) in polluted state. To allow disposal of the container in cramped spaces and to eliminate the risk of explosive and/or toxic gases collecting therein, the container is characterized in that it comprises an outer container (64) and an inner container (66), that there is connected to the inner space (65) of the outer container (64) and possibly to the inner space (72) of the inner container (66) a pump device (75 and possibly 79) for pumping up clean detergent (73) from the inner space (65) of the outer container (64) and possibly the inner space (72) of the inner container (66), that there is connected to the inner space (72) of the inner container (66) a return conduit (29) for recirculating detergent (73) coming from the outer container (64) and possibly from the inner container (66) and polluted through use, to the inner space (72) of the inner container (66), and that the inner container (66) has flexible walls to permit unfolding and/or distention thereof as the outer container (64) is drained of clean detergent (73) and the inner container (66) is filled with polluted detergent (73). (FIG. 3).
